基于区块链的病死害动物无害化处理模型
|
摘要
病死害动物随意丢弃和流入市场会严重影响环境卫生与食物安全,传统基于射频识别(radio frequency identification,简称RFID)技术溯源流程构成的中心化监控网络,存在诸多挑战。将区块链技术引入病死害动物的监控网络,有效提升了监控效力与群众信任度,主要体现在:(1)采用去中心化结构,克服了传统监管流程存在的弊端,确保流程可信度;(2)通过智能合约技术最小化恶意或意外事件发生的可能性,降低合约欺诈所造成的损失;(3)采用基于对等网络的分布式账本数据库,保证系统安全稳定。将区块链技术用于病死害动物监控,能极大地提升监控效果、政府公信力、群众安全感,避免农户及非法处理机构不自觉所导致的安全隐患。
